CALENDAR.

Specification of Letters Patent.

Patented Aug. 17, 1920.

Application filed September 10, 1919. Serial No. 322,894.

To all whom it may concern.

Be it known that I, PINUUS Rica, citizen of the United States, andresident of New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Calendars, ofwhich the following is a specification.

This invention relates to calendars and particularly to the so calledperpetual calendars.

The objects of my invention are to provide a simple, inexpensive andhandy mechanism which may be easily operated, and which, .in view of itsprimitive construction, is not liable to get out of order.

Other objects are to provide a mechanism so constructed, as to beoperable by a frictional or gear-engagement combined with a rotarymotion, while eliminating any sort of spring actions, lockingarrangements or similar devices which, in the course of use might failto function.

Still other objects are to provide means whereby the calendar casing maybe easily attached to or detached from a typewriter frame or any otherobject where a calendar is of importance.

The above and further objects will appear more fully in the followingspecification and from the accompanying drawings, forming a partthereof, in which Figure 1 is an elevation of my device, attached to atypewriter frame.

Fig. 2 is an end view of same.

Fig. 3 is a sectional view of my device, taken on line 3-3 of Fig. 1.

Fig. 4 is an enlarged longitudinal cross sectional view of one preferredform of my device.

Fig. 5 is a similar sectional View of an other form of my device.

Fig. 6 is a sectional view taken on line (3-6 of Fig. 4.

Referring to the figures, a typewriter frame 1, is shown, to which mycalendar is attached by means of spring clamps 2 and 3, secured to theslidable base plate 4. The base plate shown in Fig. 5 is provided withcountersunk holes 5 for receiving a screw or rivet with which the platemay be fastened to any desired article. As illustrated, the base-platepossesses turned-up extensions 6 provided with longitudinal groovesregistering with guides 7 of the calendar casing 8.

This casing is provided at its semi-cylindrical upper part withapertures 9, 10, 11

and 12, in its side-walls with side-bearings I13, and with a centralgroove 14 for receiving a dividing center wall 15 equipped with athrough-going center bearing 16 which is alined 'with the end-bearings13. Upon the outer surface of each of the side-bearings are mountedhollow cylindrical dating members 17 and 18, and upon each end of thethroughgoing center bearings are secured similar dating members 19 and20.. All of the cylinders are rotatable and in a slight frictionalengagement with the bearings and are provided upon their outer surfacewith either paper strips 21. or other means for indicating months,numbers and days.

Passing through the outer bearings into the center bearing are shafts 22and 23 equipped with engaging members 24 and 25, which are securelyfastened to the shafts by set-screws 26. By pressing one of theseengaging members toward a dating member, through shifting the respectiveshaft in the proper direction, that dating member maybe turned, when theknurled knob 27 of the shaft is turned, until set into desired position.

In Fig. 4 are shown engaging members of a double cone-shaped formcorresponding with funnel-shaped dating members, which extend beyond, oroverhang their shorter bearings. In Fig. 5 is shown an engaging memberof a different shape, having a rim 2S equipped at its edges 29 eitherwith friction bands or teeth, for engaging similar engaging meansprovided upon its corresponding dating members. In the latter form thepart of the dating members resting upon the bearings may be of the samelength as the latter.

Both constriuztions adhere to the basic principle of operating aperpetual calendar by means of a pair of slidable shafts having engagingmembers firmly secured to them, said members operatively engaging thedating mechanism of the calendar, one unit at the time, by shifting theshaft, and with it the engaging member, toward the one dating member andthen turning the same by turning the shaft, until the desired words ornumbers appear within the apertures of the casing. In both cases thedating members are in slight frictional engagement with their respectivebearings so as to prevent the dating members from voluntarily turning,permitting them however to be operated by their respective engagingmembers. The

. the broad principle of my idea. The same applies to changes orimprovements of the attaching means for securing my device to variousarticles. Also the shape or construction in general shall not belimited. to the forms shown, and changes may be made to meet differentconditions or requirements within the broad scope of my invention.

Having thus described my invention and the principal features of itsoperation, I claim:

1. In a perpetual calendar operated by frictional devices, a main casinghaving side bearings, a center wall having a through going centerbearing alined with said side bearings, two hand operated shafts, eachpassing through one side bearing and into the center bearing,double-cone-shaped friction members rigidly attached to said shaftsbetween the bearings, dating members rotatably mounted upon the outersurfaces of the bearings and overhanging the same, permitting theirengagement by said friction members.

2. The combination with a perpetual calendar, of a housing having endbearings, a slidable center wall inserted into grooves provided in saidhousing, a through-going center bearing provided in said center wall andalined with said end bearings, hand operated shafts passing through saidend bearings into the center bearing, without touching each other,engaging members rigidly secured upon each of the shafts between theside bearings and center bearing, dating members rotatably mounted uponthe outer surfaces of the bearings and operable independently by saidengaging members at will, and means for attaching the calendar to atypewriter frame.

3. The combination with a perpetual calendar, of a calendar casinghaving inwardly projecting end-bearings at each end, apertures providedat one side of the casing, a center bearing alined with theend-bearings, dating-members rotatably mounted upon the outer surface ofthe bearings and frictionally engaging the latter, means provided uponthe outer surface of said dating-members indicating month, numbers anddays, said indicating means being visible in part through said aperturesin the casing, an engaging member between the month indicatingdating-member and one number indicating dating-member, another engagingmember between the other number indicating dating-member and the dayindicating dating-member, hand-operated shafts slidably and rotatablylodged in said bearings, each shaft having one engaging member rigidlyattached thereto, a base plate for the casing, attaching means connectedtherewith for facilitating the fastening of the calendar to a desiredobject, said shafts, when pressed inward or pulled outward of the casingand simultaneously turned, causing the engagement of said engagingmembers with, and the turning of said dating members to a desiredposition.

at. In a calendar of the class described comprising a casing, inwardlyextending bearings secured to the end walls of the casing, rotatabledrums having upon their periphery dating characters mounted upon thebearings, and means disposed between and normally out of contact withsaid drums and adapted for movement into positive engagement with eitherof said drums for actuating the same.

5. In a calendar of the class described comprising a casing, inwardlyextending tubular bearings secured to the end walls of the casing,members having upon their periphery dating characters rotatably mountedon the tubular bearings, and means normally out of contact with the endsof the members and adapted to be optionally shifted into positiveengagement with either of said members for actuating the same.

6. In a calendar of the class described comprising a casing having sidebearings, dating members rotatably mounted upon the outer surfaces ofthe bearings, and an operating shaft journaled and slidably mountedwithin the bearings having rigidly secured thereon a member disposedbetween the dating members normally out of contact PINGUS RICE.
